Amy Rose is a hedgehog from Sonic's planet. She has a REALLY HUGE crush on Sonic, but is also his very close friend. She's also best friends with Cream, and is also a close friend to Tails and Knuckles.
Amy is a sweet and caring girl who is always willing to help others. However, she can be extremely stubborn, never taking the hint that Sonic doesn't like her in the way she likes him. Amy is known to be agressively short tempered, punching things out of rage with her Piko Piko hammer. Knuckles will often try to stop Amy from her violent ways but she refuses.
